Turn off the water supply to the Aqua Magic SL toilet. You may need to refer to your RV's instruction manual for the water shut-off location.
Disconnect the fresh water supply line on the rear of the toilet with a pair of slip joint pliers. Press down on the flush foot pedal and insert a wood block inside the slide trap to hold the foot pedal down.
Locate the front mounting flange bolt behind the foot pedal. Remove the nut securing the front of the Aqua Magic SL toilet to the front flange bolt with a socket wrench. Press down on the foot pedal and remove the piece of wood.
Lift the toilet seat and lid and locate the access cover on the toilet that hides the rear flange bolt. Pry the cover off the toilet with a flathead screwdriver.
Remove the retaining nut securing the rear of the Aqua Magic SL to the floor with a socket wrench. You will need a 12-inch extension on your socket wrench to reach the retaining nut. Grab the Aqua Magic SL on both sides and lift the toilet off the flange bolts and away from the work area.
